89225e8e84d38b07a8335922497997e83d872e75jim a bit clunky on some platforms; eg, on Linux, the loop to
89225e8e84d38b07a8335922497997e83d872e75jim join each worker thread seems to hang, and the parent ends up

74e7a30182af5e68f14ccb8d57918b22b982db8bhumbedooh But the right answer is to fail the request up-front in dir/file

60a765cccbd3f3b5997b65b0034220c79f78369etrawick correctly since filters were added because it wasn't possible to

ec7520b24cd80d34d82bbcaca153cbb23cc04bc0rjung * Handling of %2f in URIs. Currently both 1.3 and 2.0
ec7520b24cd80d34d82bbcaca153cbb23cc04bc0rjung completely disallow %2f in the request URI path (see
ec7520b24cd80d34d82bbcaca153cbb23cc04bc0rjung ap_unescape_url() in util.c). It's permitted and passed
6249dfa569d3b4f1f539665b979a80c6e335d93etrawick through in the query string, however. Roy says the
6249dfa569d3b4f1f539665b979a80c6e335d93etrawick original reason for disallowing it, from five years ago,
0827cb14e550f6f65018431c22c2c913631c8f25kbrand was to protect CGI scripts that applied PATH_INFO to
6249dfa569d3b4f1f539665b979a80c6e335d93etrawick a filesystem location and which might be tricked by
ae600ca541efc686b34f8b1f21bd3d0741d37674covener ..%2f..%2f(...). We *should* allow path-info of the

cfa64348224b66dd1c9979b809406c4d15b1c137fielding * FreeBSD, threads, and worker MPM. All seems to work fine
74499a117b3b2cd9666715a14f90c0e5d1a4ee8ajim if you only have one worker process with many threads. Add
cfa64348224b66dd1c9979b809406c4d15b1c137fielding a second worker process and the accept lock seems to be
74499a117b3b2cd9666715a14f90c0e5d1a4ee8ajim lost. This might be an APR issue with how it deals with
cfa64348224b66dd1c9979b809406c4d15b1c137fielding the child_init hook (i.e. the fcntl lock needs to be resynced).
More examination and analysis is required.
Status: This has also been reported on Cygwin.
Message-ID: <3C2CC514.8EF3BED1@wapme-systems.de> (cygnus)
Justin says: So, FreeBSD-CURRENT and Cywin have the same
problem. Yum. If another platform has this
with worker, this becomes a showstopper.
Aaron says: I spent some time disecting this and have come to
the conclusion that it is not a problem in the worker MPM
(or at least, it is not isolated to a problem in worker).
I'll list some of the problems I'm seeing in case someone
else wants to pick up where I've left off:
- Delivery of just about any signal to one of the child
processes will send it into an infinite loop as well.
- Even though the parent is spinning out of control,
at first the child or children will appear to work
properly. At times it is possible to get it into a state,
however, where a request will hang until another concurrent
request "kicks" the first, at which point the second will
hang. My theory is that this has to do with the
pthread_cond_*() implementation in FreeBSD, but it's still
possible that it is in APR.
Justin adds: Oh, FreeBSD threads are implemented entirely with
select()/poll()/longjmp(). Welcome to the nightmare.
So, that means a ktrace output also has the thread
scheduling internals in it (since it is all the same to
the kernel). Which makes it hard to distinguish between
our select() calls and their select() calls.
*bangs head on wall repeatedly* But, some of the libc_r
files have a DBG_MSG #define. This is moderately helpful
when used with -DNO_DETACH. The kernel scheduler isn't
waking up the threads on a select(). Yum. And, I bet
those decrementing select calls have to do with the
scheduler. Time to brush up on our OS fundamentals.
* There is increasing demand from module writers for an API
that will allow them to control the server � la apachectl.
Reasons include sole-function servers that need to die if
an external dependency (e.g., a database) fails, et cetera.
Perhaps something in the (ever more abused) scoreboard?
rbb: I don't believe the scoreboard is the correct mechanism
for this. We already have a pipe that goes between parent
and child for graceful shutdown events, along with an API that
can be used to send a message down that pipe. In threaded MPMs,
it is easy enough to make that one pipe be used for graceful
and graceless events, and it is also easy to open that pipe
to both parent and child for writing. Then we just need to
figure out how to do graceless on non-threaded MPMs.
* Allow the DocumentRoot directive within <Location > scopes? This
allows the beloved (crusty) Alias /foo/ /somepath/foo/ followed
by a <Directory /somepath/foo> to become simply
<Location /foo/> DocumentRoot /somefile/foo (IMHO a bit more legible
and in-your-face.) DocumentRoot unset would be accepted [and would
not permit content to be served, only virtual resources such as
server-info or server-status.
This proposed change would _not_ depricate Alias.
* Win32: Rotatelogs sometimes is not terminated when Apache
goes down hard. FirstBill was looking at possibly tracking the
child's-child processes in the parent process.
OtherBill asks, wasn't this fixed?
stoddard: Not fixed. Shared scoreboard might offer a good
way for the parent to keep track of 'other child' processes
and whack them if the child goes down.
Other thoughts on walking the process chain using the NT kernel
have also been proposed on APR.
* Win32: Add a simple hold console open patch (wait for close or
the ESC key, with a nice message) if the server died a bad
death (non-zero exit code) in console mode.
Resolution: bring forward same ugly hacks from 1.3.13-.20
* Port of mod_ssl to Apache 2.0:
The current porting state is summarized in modules/ssl/README. The
remaining work includes:
(1) stablizing/optimizing the SSL filter logic
(2) Enabling SSL extentions
(3) Trying to seperate the https filter logic from mod_ssl -
This is to facilitate other modules that wish to use the https
filter or the mod_ssl logic or both as required.
* Eliminate unnecessary creation of pipes in mod_cgid
* Combine log_child and piped_log_spawn. Clean up http_log.c.
Common logging API.
* Document mod_file_cache.
* Platforms that do not support fork (primarily Win32 and AS/400)
Architect start-up code that avoids initializing all the modules
in the parent process on platforms that do not support fork.
* Win32: Migrate the MPM over to use APR thread/process calls. This
would eliminate some code in the Win32 branch that essentially
duplicates what is in APR.
* There are still a number of places in the code where we are
losing error status (i.e. throwing away the error returned by a
system call and replacing it with a generic error code)
* Mass vhosting version of suEXEC.
* All DBMs suffer from confusion in support/dbmmanage (perl script) since
the dbmmanage employs the first-matched dbm format. This is not
necessarily the library that Apache was built with. Aught to
rewrite dbmmanage upon installation to bin/ with the proper library
for predictable mod_auth_dbm administration.
Questions; htdbm exists, time to kill dbmmanage, or does it remain
useful as a perl dbm management example? If we keep it,
do we address the issue above?
* Integrate mod_dav.
Some additional items remaining:
- case_preserved_filename stuff
(use the new canonical name stuff?)
- find a new home for ap_text(_header)
- is it possible to remove the DAV: namespace stuff from util_xml?
* ap_core_translate() and its use by mod_mmap_static and mod_file_cache
are a bit wonky. The function should probably be exposed as a utility
function (such as ap_translate_url2fs() or ap_validate_fs_url() or
something). Another approach would be a new hook phase after
"translate" which would allow the module to munge what the
translation has decided to do.
Status: Greg +1 (volunteers), Ryan +1
* Explore use of a post-config hook for the code in http_main.c which
calls ap_fixup_virutal_hosts(), ap_fini_vhost_config(), and
ap_sort_hooks() [to reduce the logic in main()]
* read the config tree just once, and process N times (as necessary)
* (possibly) use UUIDs in mod_unique_id and/or mod_usertrack
* (possibly) port the bug fix for PR 6942 (segv when LoadModule is put
into a VirtualHost container) to 2.0.
* shift stuff to mod_core.h
* callers of ap_run_create_request() should check the return value
for failure (Doug volunteers)
* Win32: Get Apache working on Windows 95/98. The following work
(at least) needs to be done:
- Document warning that OSR2 is required (for Crypt functions, in
rand.c, at least.) This could be resolved with an SSL library, or
randomization in APR itself.
- Bring the Win9xConHook.dll from 1.3 into 2.0 (no sense till it
actually works) and add in a splash of Win9x service code.
* In order to use a DSO version of mod_ssl we have to link with
-lssl and -lcrypto. A workaround is in place right now where the
entire EXTRA_LIBS macro is being appended to the objects list, but
this is a hack. We should either revamp the APACHE_CHECK_SSL_TOOLKIT
autoconf function or come up with some other autoconf checks to
search for libssl and libcrypto and properly add them to mod_ssl's
link flags.
* Fix the worker MPM to use POD to kill child processes instead
of ap_os_killpg, regardless of how they should die. (Ryan Bloom)
* Scoreboard structures could be changed in the future such that
proper alignment is not maintained, leading to segfaults on
some systems. Cliff posted a patch to deal with this issue but
later recanted. See this message to dev@apr.apache.org:

EXPERIMENTAL MODULES:
Experimental modules should eventually be be promoted to fully supported
status or removed from the repository entirely (ie, the
'experiment' failed). This section tracks what needs to happen to
get the modules promoted to fully supported status.
mod_cache/mod_mem_cache/mod_disk_cache:
* mod_cache: handle cache_control: no_cache "field_name" to enable
cacheing the response w/o header "field_name"
See RFC2616 section 14.9.1
* mod_cache: CacheEnable/CacheDisable should accept regular expressions.
* mod_cache: Fix dependency on ATOMIC operators. Need
APR_HAS_ATOMIC_* feature macros.
* mod_disk_cache: Implement garbage collection
* mod_mem_cache/mod_disk_cache: Need to be able to query cache
status (num of entries, cache object properties, etc.).
mod_status could be extended to query optional hooks defined
by modules for the purpose of reporting module status.
mod_cache (et. al.) could define optional hooks that are called
to collect status. Status should be queryable by
HTTP or SNMP?
* mod_mem_cache: garbage collection. One strategy is to simply
remove stale entries as we attempt to serve them. Another
strategy is to kick off a GC thread that traverses the cache
and preemptively remove stale entries. How to manage a
cache that is full? Do LRU GC? Other? Bueller?
* mod_mem_cache/mod_disk_cache: Complete implementing config
directives.
* Sample config for mod_cache/mod_mem_cache/mod_disk_cache for
inclusion into httpd.conf.
* mod_cache/mod_mem_cache/mod_disk_cache: Documentation.

Suggestion for better handling of Last-modified headers
Status:

mod_cgi prevents handling of OPTIONS requests
Status:
* PR#5713: os-windows
[PATCH] install as win32 service with domain account
Status: Cannot accept password-as-arg, we should prompt the
user when -k install/-k config with a user argument.
* PR#5993: general
AllowOverride should have a 'CheckNone' and 'AllowNone' argument
instead of only 'None'
Status:
Other bugs that need fixing:
* ap_discard_request should be converted to use the bucket API
directly rather than waste cycles copying buffers with the old API.
* MaxRequestsPerChild measures connections, not requests.
Until someone has a better way, we'll probably just rename it
"MaxConnectionsPerChild".
* Regex containers don't work in an intutive way
Status: No one has come up with an efficient way to fix this
behavior. Dean has suggested getting rid of regex containers
completely.
OtherBill suggests: We at least seem to agree on eliminating
the <Container ~ foo> forms, and using only
<ContainerMatch foo> semantics.
* SIGSEGV on Linux (glibc 2.1.2) isn't caught properly by a
sigwaiting thread. We need to work around this, perhaps unless
there is hope soon for a fixed glibc.
* orig_ct in the byterange/multipart handling may not be
needed. Apache 1.3 just never stashed "multipart" into
r->content_type. We should probably follow suit since the
byterange stuff doesn't want the rest of the code to see the
multipart content-type; the other code should still think it is
dealing with the <orig_ct> stuff.
Status: Greg volunteers to investigate (esp. since he was most
likely the one to break it :-)
